RAIL-ANCHOR.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed. July 12, 1915. Serial No. 39,280.

To all whom it may concern Be it known that 1, JOHN F. OCONNOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Rail-Anchors, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in rail anchors.

An object of the invention is to provide a relatively cheap anti-rail creeper or anchor having means for automatically maintaining an effective grip on the rail at all times.

' sectional View taken substantially on the line 3-3 of Fig. 2.

In said drawing, 10 denotes a tie and 11 a rail of the usual construction having a base 12, the upper surfaces 13 of which are inclined relatively to the bottom horizontal face 1 1.

The improved rail anchor designated generally by the reference A consists, as shown, of two clamp members C-C of like construction and a spring steel key 15. Each of the members C is in the form of a clamp adapted to grip an edge of the rail base and to this end is provided with an upper longitudinally extending flange 16, the under surface 17 of which is beveled to wedge against the upper surface 13 of the rail base, and a lower section 18 extending beneath the rail base, said section 18 being provided with a plurality of spaced fingers 19-19, the latter having upwardly extending shoulders or bosses 20-20 rounded on their outer faces as indicated at 21 and also slightly rounded or chamfered on their inner faces as indicated at 22. The fingers and shoulders 19and 20 of one member G are alternated with respect to the corresponding fingers and shoulders of the other member so that when the two members are assembled as clearly indicated in Fig. '2, the key 15 can be inserted therebetween and longitudinally of the rail. The key 15 is preferably made of comparatively heavy spring steel so that it will flex in passing the shoulders 20 and its elasticity after the key has been driven home will prevent the separation or loosening of the clamp members CG under vi bration. Furthermore, the slight set in the key 15 after it has been driven home will prevent the key itself from workingout.

From the foregoing description, it will be seen that the rail anchor is relatively cheap to manufacture since the two members CG are of like construction and may be cast from the same pattern and the key 15 will automatically retain the members CC in effective gripping engagement with the rail. As clearly indicated in the drawing, the members CO will engage the tie and consequently prevent creeping of the rail.

I claim:

1. A rail anchor comprising two clamping members arranged to grip the opposite edges of a rail base, said members having a plurality of shoulders located below the rail base, and a resilient member extending between said shoulders and thereby retaining said members in gripping engagement with the rail. 2. A rail anchor comprising two clamping members arranged to grip the opposite edges of a rail base, said members being provided with alternately arranged spaced shoulders, and a spring member extending lengthwise of said clamping members and between the alternated shoulders.

8. A rail anchor comprising two like clamping members arranged to grip the'opposite edges of a rail base, each of said members having a. plurality of spaced tingers extending beneath the rail base, the fingers of one member being alternated with the fingers of the other member and all provided with upstanding bosses, and a retaining plate inserted between said bosses.

4. A rail anchor comprising two clamping members arranged to grip the opposite edges of a rail base, each of said members having a plurality of spaced fingers extending beneath the rail base,the fingers having upstanding shoulders near their ends, and a spring key inserted lengthwise of the rail between said shoulders and thereby yieldingly maintaining said clamping members in gripping engagement with the rail base.

5. A rail anchor comprising two like castings of substantially hook shape in cross section and arranged to grip the edges of a rail base, each of said members being provided With a plurality of spaced fingers extending beneath the rail base, each ofsaid fingers having an upstanding boss near the end thereof, the fingers and bosses of -one member alternating With those of the other member, said clamping members being also JOHN F. OCONNOR.
